Things are building up for a big season finale of “Arrow,” and this week’s new episode, “Streets f Fire,” looks to raise the stakes even more for this season’s final episode, as a familiar face will be showing up again in the fight against Slade and his army. Executive Producer Andrew Kreisberg recently spoke at press Q&A where he shares some more details on this character’s return. Below is what Andrew Kreisberg had to say, as well as two new images from the episode. But if you want to stay absolutely spoiler free on the episode and not know who’s returning, it’s best if you don’t read the quotes from Andrew Kreisberg or see the images.

Spoilers Below:

“All hell is going to break loose in the city and Thea will find herself in a precarious predicament, and she will be saved by her father. And Malcolm is going to offer her what she doesn’t have anymore.”

“That was part of our math with killing Moira — that if we were going to send Thea in that direction, she needed to have nothing pulling her back here. Now she has a brother who lied to her and has done something unforgivable, and no mother. And on the flip side, she has Malcolm Merlyn saying, ‘I will never lie to you, Thea.’”
